Screenshot 1

Here, you can see two changes to the original program:
1) The text follows the top of the monster, rather than
being in the middle of the screen.
2) Text longer than 7 characters shows the last 7 rather
than the first 7 characters.
'/sbin/mingetty' is shown as 'ingetty' rather than
'/sbin/m'
